Researchers working in Finland propose that the unique light environment of the Earth’s Polar regions creates conditions that result in circumpolar hybrid zones around the North and the South Poles. These extreme conditions increase the synchrony of reproductive phenology among species, i.e., force all species into a smaller window for reproduction. This will sustain biodiversity in the long term.
